the hiding/showing is part of what i used for my rainbow filters! its a little more complicated, but i go iover it in the same tutorial ^^ https://solaria.neocities.org/jscheats#filter
is that post about hiding/showing content close to what you used for the tags on your rainbows? I'm thinking of implementing something similar on a fantasy timeline i've got and i'm a js noob, and your tutes are great :0
finally added alt text for buttons and blinkies!
homepage is much more accessable, other pages will need work, stamps page has no alts at all
going back and adding things like this is very tedious to my adhd brain, but i think its important
